Yeah it had two driver seats, one in the front one in the back. It's rare but there are other examples liek Panzerspähwagen and the Italian Autoblinda 41. It also had 10 gears, 5 forward and 5 reverse.
The original intention was to operate it with a crew of four because it was uncomfortable and time consuming for the driver to crawl to the back but I guess it could function without a dedicated second driver as one of the crew members at the turret could pick up that role if needed be.
tl;dr Crew: 4.
